The first known semi-natural appearance of this oscillator was in December 2014, in a symmetric soup found by Dongook Lee using apgsearch.[2]

A 46-glider synthesis of this oscillator was found by Jeremy Tan on January 5, 2020.[3]

gollark: So it turns out that heavpoot was right and the interbridge bridge code is awful and full of apiaries and now I don't know how virtual channels should work.
gollark: This is much more elegant than the horrors of apiotelephone routing.
gollark: Exciting news: an early virtual channel implementation in ABR is working okayish.
gollark: I've now realized that I can ignore those in the simple case, and I can just make the case always be simple, so it's fine.
gollark: I've realized VARIOUS flaws with my idea and now all is bee. Not that I implemented it. But all will become bee.
